Software Update: Quicktime 7.1.1

Apple released an update to Quicktime this afternoon, version 7.1.1. According to the support page, it "addresses an issue with 3rd party start-up items on Intel Macs. This release also fixes an issue exporting to Keynote presentations to iDVD. Also delivers numerous bug fixes, support for iLife06, and H.264 performance improvements."

Does anyone know specifically what 3rd-party startup items this is talking about?
